CryptoEngine
CryptoEngine (C) is a DLL Library that provide Cryptography Services.
CryproEngine (C) is a Class Library (DLL) that provide (API) interface, programmer can use it when writing applications that needs Standard Cryptography Algorithms, using Qt-SDK. Actually this library is a Wrapper for Crypto++ library, by Wei Dai, which is approved by NIST (see www.cryptopp.com for details), CryptoEngine is intended to provide simple & easy to use interface (API) for standard cryptography algorithms for Qt-SDK Developers. -

MOTE CSPRNG & Stream Cipher
A family of small-state CSPRNGs and Stream Ciphers
MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only... -

The MOTET Cipher & SE Scrambler
A tiny, fast encryption tool in C
MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage. A unique nonce IV guarantees that... -

CryptoPad v1.0
AES-128 bit file encryptor
CryptoPad is a Java based file encryptor ! It can encrypt every type of file. The icing on the cake is that it's 100% cross-platform. i.e. You can run the same .jar file on Windows, Mac OS, Linux and any OS capable of running JRE 8 :) CryptoPad uses AES-128 bit symmetric key encryption to secure your data. -

Checksum Directory
Check some checksum!
A secure and centralized way to get checksums of common downloads. You will find the usual MD5 hash, but also the newer and more secure hashes like SHA-1, SHA-256 and even SHA-512. If the filesize and all up to four hashes match, you should be save to use that downloaded file. -

ISC - The ISAAC Stream Cipher
ISC lets you encrypt & decrypt text and files of any type up to 4GB
ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any... -

ImpraStorage
ImpraStorage provided a private imap access to store large files
ImpraStorage provided a private imap access to store large files. Each file stored on the server is split in severals random parts. Each part also contains random noise data (lenght depends on a crypt key) to ensure privacy and exclude easy merge without the corresponding key. An index of files stored is encrypt (with the symmetric-key algorithm Kirmah) and regularly updated. Once decrypt, it permit to perform search on the server and download each part. transfert process is... -

SSL Diagnos
SSL Strength Evaluation and Test Utility
SSL Diagnos is used to test SSL strength; get information about SSL protocols (pct, ssl2, ssl3, tls, dtls) and cipher suites. It can also be used for testing and rating ciphers on SSL clients. It has also specific support for pop3s, sip, smtp and explicit ftps. Tests for heartbleed (including dtls). Furthermore a separate tool, SSLPressure, not using openssl can be used to check the whole spectrum of possible SSL protocols on a server. Can also be used for testing ssl for... -

Python3 GnuPGInterface (GPG)
Python3 GPG aka GnuPG Interface
Python3 port of Frank Tobin's Python GnuPGInterface incorporating the --keyring and --secret-keyring patch. "Python GnuPGInterface is meant to be a filehandle-concentrating Python interface to GnuPG, the GNU Privacy Guard. It has an API similar to the Perl module GnuPG::Interface" and identical to the Python2 module GnuPGInterface. -

Bigram Table Generator
A program to generate random reciprocal bigram tables
A command-line program to encrypt/decrypt a message using a random reciprocal bigram table and write a bigram table to a text file. Executing the program without any command-line arguments starts bigram in message encryption/decryption mode. The program prompts for a password or passphrase and a message to encrypt/ decrypt. After the message is entered the ciphertext is displayed. Executing the program with command-line arguments causes bigram to generate a random bigram table to... -

innocence-java
Replace text with POS equivalent text, in a reversible fashion.
Program takes (currently) english text sentences, and replaces each word in a given sentence with another word having the same Part of Speach (POS) tag. This creates a new sentence containing none of the original words. This new sentence can then be transmitted to a remote user, and using the same software, "de-crypted" into yielding the original sentence. The software relies on having a known "seed" value for the random number generator, which is known only by the sender and... -

Azrar
Encryption addressing long-term data secrecy
Most of today's cryptographic standards will be broken with tomorrow's computational power. Azrar is a user-friendly tool for the encryption/decryption of single files - preferably compressed archives - addressing long-term data secrecy. Thus, Azrar provides the possibility to use webspace for secure data transfer between two communication/transfer partners (encryption only, network transfer not yet included in current version). Data in encrypted files are secret/private indefinitely. To... -

JCryptor
JCryptor is an encrypting tool based on the Caesar-cipher.
JCryptor uses the Caesar-cipher to encrypt keystrokes on-the-fly. It can also be used to decrypt an encrypted text easily. Caesar-cipher is a simple encryption algorithm, developed by Julius Caesar, to encrypt his correspondence with Cicero in the ancient world. Therefore it uses a simple character substitution method to replace a given character by another. A keyshift of thirteen is called ROT13. ROT13 can be decrypted by encrypting it again with ROT13. Even today this simple method is used... -
